Meaning of “Delusions of Grandeur”
”Delusions of grandeur” is a term that is used to describe a false or inflated belief that one has higher status or powers than one actually possesses. This term is used to describe individuals who have an exaggerated view of their own importance or ability, sometimes even to the extent of being delusional.
In a clinical setting, the delusion of grandeur is seen as a manifestation of some psychiatric disorders including bipolar disorder, schizophrenia or narcissistic personality disorder. However, this term is also very popular in colloquial language to refer to anyone who has an inflated ego or excessive desire for success.
Delusions of grandeur are characterized by the belief that one has exceptional abilities, affiliations, or abilities that are not factual. These beliefs make the individual arrogant, which means that he or she behaves as if he or she deserve special attention or consideration. At times, these delusions may lead to behaviors that are dangerous, unreasonable or even violent, because the affected individual’s ego may make him or her act in a manner that is unwise or hazardous to others.
In a more general sense, the term “delusions of grandeur” is commonly employed to refer to cases where individuals or teams have inflated perceptions of their power, effectiveness, or significance. This can be applicable to anyone from a political leader who feels he or she is unbeatable, an artist who feels he or she has created the next big thing, or a company that has underestimated the effects of their products on the market.
Origin of “Delusions of Grandeur”
The phrase “delusions of grandeur”, has its origins in the realm of psychiatric and medical terminology and practice. Although, the general idea of grandiosity has been known for centuries with Hippocrates and Galen mentioning symptoms that are familiar with this disorder, the term as such appeared later. This phrase can be traced back to the 19th century when the language of psychiatry was rapidly expanding.
In 1852, French psychiatrist Jean-Pierre Falret used the term “délire de grandeur”, or the delusion of grandeur as a symptom of what we now know to be bipolar disorder. This concept was further expanded upon by German psychiatrist Emil Kraepelin in his study of dementia praecox, later known as schizophrenia, where grandiose delusions were noted to be a major feature.
The English term delusions of grandeur has been in use since the early part of the twentieth century and could be found in medical journals and psychiatric texts where it was translated from the French as délire de grandeur or from the German as Größenwahn.
Delusions of grandeur as a concept emerged in the mid-20th century and was introduced into the field of psychiatry. This is because the Diagnostic and Statistical Manual of Mental Disorders (DSM) listed grandiose delusions as a symptom of different disorders hence giving it credibility.
Interestingly, the phrase is a direct translation of the French ‘délire de grandeur,’ and in German, the term ‘Größenwahn’ (meaning ‘size illusion’) is used to describe the same phenomenon.
Through time, the term delusions of grandeur is no longer limited to the medical profession and has become a part of the colloquial language. It is a conversational phrase that can be employed in a comedic or sarcastic manner to refer to someone who believes they are better than others.
This shift from medical language to everyday slang shows how psychological ideas can enter the collective imagination. Today, the more “specific term of “grandiose delusions” is used in psychiatry, but the phrase “delusions of grandeur is still used in literature, film, and even in the spoken language, which witnesses to its continued applicability to the description of a certain aspect of people’s psychology.
Use of “Delusions of Grandeur” in Literature
In literature, a number of writers have used the phrase “delusions of grandeur” in an attempt to examine the prospective of ambition, hubris and possible repercussions of over-estimating one self.
It has been applied to generate characters whose primary motivation is their self-image, which always results in tragedy or comedy. In the following part of the article, several examples of how the term “delusions of grandeur” has been used in literature and their relevance are explored.

Example#1
“One Flew Over the Cuckoo’s Nest” by Ken Kesey
“McMurphy had no more than ordinary delusions of grandeur. He didn’t think he was God; he just thought he could beat the game.”
In the novel, Ken Kesey resorts to “delusions of grandeur” to portray McMurphy as a rebellious character who defies the tyranny of Nurse Ratched and the authority of the mental hospital.
Although McMurphy thinks that he is capable of beating the system, the narrator (Chief Bromden) ascribes this optimism to be what he considers a petty form of paranoia — one not so unhealthy in the least.
McMurphy does not consider himself a godlike figure but he realized that he could perform superhuman feats. Here, the phrase has been employed to stress the fact that Mcmurphy overestimated himself and the extent to which he could fight the system.
Example#2
“Catch-22” by Joseph Heller
….’That’s some catch, that Catch-22,’ he observed. ‘It’s the best there is,’ Doc Daneeka agreed. Yossarian saw it clearly in all its spinning reasonableness. There was an elliptical precision about its perfect pairs of parts that was graceful and shocking, like good modern art, and at the same time it was terrible and paradoxically preposterous. It made perfect sense. It was a crazy delusion of grandeur, not to be doubted, not even a little.”
In “Catch-22”, the writer uses the phrase “delusion of grandeur” more figuratively. Yossarian, the protagonist, is still struggling to make some sense of the circularity of Catch-22 which is a military rule that frustrates the protagonist and his comrades.
Here, the “delusion of grandeur” implies that the military bureaucracy has a perfect system of work even if they consider it to be insane. The phrase is to explain how one can come up with large structures of ideas or operations that are illogical yet are considered above reproach.
Example#3
“American Psycho” by Bret Easton Ellis
“There is an idea of a Patrick Bateman, some kind of abstraction, but there is no real me, only an entity, something illusory. And though I can hide my cold gaze, and you can shake my hand and feel flesh gripping yours and maybe you can even sense our lifestyles are probably comparable… I simply am not there. It is hard for me to make sense on any given level. My self is fabricated, an aberration. I am no longer a man, but an entity with delusions of grandeur.”
In his novel, the author employs term “delusions of grandeur” to describe the psychological condition of the main character, Patrick Bateman. The complex and rather paradoxical protagonist, Bateman, a prominent Wall Street player-Monster, studies the twofold aspect of his soul and mind losing connection with reality and perceiving himself as a mere puppet behind the professional mask.
His ‘hallucinations’ underscore his arrogance or more like a superiority complex and portrays him as a person who cannot differentiate between himself and the heroic figure he has conjured in his mind. The phrase here is used to depict him as mentally ill and to exaggerate his sense of self-importance.
Example#4
“The Corrections” by Jonathan Franzen
“Chip’s delusions of grandeur were now delusions of adequacy. He no longer dreamed of being famous or changing the world; he was just trying to find a job that didn’t make him feel like a total failure.”
In the novel “The Corrections” there is an instance of using the words “delusions of grandeur” in relation to the character of Chip Lambert where the author tries to convey the idea of the shift from great and high-pitched goals and dreams to the relatively small and pragmatic ones.
At first, Chip wanted to change the world and truly make a difference, but eventually, as his life and mind deteriorate, even these delusions of grandeur are just attempts at simply existing while not feeling like a loser. The phrase is used to show that because of his experiences, Chip’s ego is now deflated.
